Definitions
- the present invention relates to a method and apparatus for automatically removing sediment from a pool by utilizing one or more stationary jets which establish fixed direction pathways terminating at the inlet of a leaf receiving means located in the pathway or pathways to receive leaves carried by the jets of water.
- the material or sediment which accumulates in a swimming pool includes algae, decomposed vegetation, hair, dirt, grass, and heavier materials such as sand, seed pods and water soaked leaves.
- lighter pool contaminants can be manually swept from the pool bottom and sides and placed in suspension by long handled brushes, or this can be done automatically by jet propelled pool cleaning devices which move across the water surface or over the surfaces of the pool.
- jet propelled pool cleaning devices typically employ one or more flexible sweep hoses which move sinuously over the pool surfaces in reaction to water discharged from the ends of the hoses.
- Another system for placing contaminants in suspension employs rotatable nozzles which are directed across different sectors of the pool by reason of actual rotation of the nozzle to different angular positions, or movement of an element internally of the nozzle which changes the direction of the jet Some such systems maintain the jet stream in each successive angular position for a period of time long enough that the momentum of the water extends the jet stream over a relatively large local area of the pool.
- Yet another system utilizes fixed nozzles which are aimed to direct continuous streams of water over the pool surfaces to establish a circulatory flow pattern terminating near the pool drain.
- Leaves are the typical but not the only heavier debris that must be removed from a pool. Accordingly, when the word "leaves” is used in the present specification and appended claims, it should be interpreted to include all debris of any significant weight that does not remain in suspension very long, i.e. sediment.
- the known pool cleaning systems of the prior art are not effective to direct heavier debris such as leaves to any stationary collection device, instead randomly moving such debris throughout the pool and depending upon chance movement of the debris to place it in proximity with the pool drain. Movement of the leaves is random because it is affected by many factors, such as the shape of the pool. Eddies form that attract and entrap leaves in areas of lesser turbulence, such as adjacent the pool corners and steps Trapping also occurs in areas of convergence or overlap of jet streams from rotating nozzles. Although it is conceivable that a sufficient number of rotary jets or fixed jets could be provided to develop strong water flow patterns throughout the entire pool, such an arrangement is impractical. A much larger and more expensive pump system would be required than would be necessary for filtering lighter contaminants out of the pool water.
- a method and apparatus for automatically removing sediment from a pool by utilizing a combination of local area turbulence inducing means, and a gathering pathway extending through the local regions
- the gathering pathway is a strong, relatively long length stream developed by a stationary jet.
- the stream developed by the jet is of sufficient duration and velocity that it extends over the length of most smaller pools, gathering leaves in its path and carrying them to the inlet of a leaf receiving means located in a fixed position at the bottom of the pool.
- the turbulence for moving and temporarily suspending the leaves for random travel into or adjacent the higher velocity pathways can be provided by various means known in the art. As previously indicated, these include manual devices for sweeping the pool surfaces, but preferably the means are automatic devices such as those using flexible sweep hoses or rotary jets.
- the stationary jet means comprises a first jet mounted on a side of the pool and oriented to direct water downwardly along the side of the pool and then along the pool bottom to the inlet of the leaf receiving means.
- a second jet located in the pool bottom in the pathway is oriented to develop a jet stream aligned with the pathway to augment the water velocity.
- a plurality of such stationary jets can be located throughout the pool to establish fixed direction primary pathways and fixed direction secondary pathways intersecting the primary pathways. Leaves moving in the secondary pathways are passed to the primary pathways, and the primary pathways terminate at the inlet to a leaf receiving means.
- the leaf receiving means comprises the inlet and a connecting conduit which carries the leaves to a leaf collecting means located externally of the pool.
- the leaf collecting means comprises a tank, a mount located in the tank, and a foraminous leaf collector carried by the mount and coupled to the connecting conduit for receiving the leaves.
- the pool pump draws water from the tank for circulation through the filtration system, and its discharge is back into the tank through a venturi jet which is directed into a discharge conduit emptying into the pool. This accelerates the discharge flow rate into the pool.
- the mount incorporates a handle valve means enabling separation of the mount from the tank for removal of leaves from the leaf collector.
- the present method and apparatus is operable with the conventional pump and filter system, but it is adapted also to operate in conjunction with sweep hose or rotary jet or other systems used for developing local area turbulence.
- FIG. 1 is a schematic plan view of a swimming pool equipped with the apparatus of the invention for removing leaves from the pool;
- FIG. 2 is an enlarged view taken along the line 2-2 of FIG. 1;
- FIG. 3 is an enlarged view taken along the line 3-3 of FIG. 1;
- FIG. 4 is a view taken along the line 4-4 of FIG. 3, illustrating the handle valve means in an open position
- FIG. 5 is a view similar to FIG. 4, but illustrating the handle valve means in a closed position
- FIG. 6 is an enlarged view of the collection inlet of the leaf receiving means
- FIG. 7 is a schematic plan view of a swimming pool similar to that of FIG. 1, but employing rotary jets to induce turbulence in the local areas at opposite ends of the pool;
- FIG. 8 is a schematic plan view of a larger pool employing a plurality of local area turbulence inducing means in combination with a plurality of stationary jets providing gathering streams or pathways extending through the local regions and terminating in a pair of leaf receiving means.
- FIGS. 1-6 the apparatus of the present invention is illustrated in association with a generally rectangular water filled swimming pool 10 having sides 12 and a bottom 14.
- a generally rectangular water filled swimming pool 10 having sides 12 and a bottom 14.
- the system illustrated is typical, including an inlet conduit 16 which carries water to the inlet side of a pump 18 whose discharge is connected to the inlet side of a filter 20 for discharge through an outlet conduit 22.
- the inlet conduit 16 is selectively coupled through valves 24 and 26, respectively, to a conventional pool skimmer 28 opening out of a side of the pool, and a leaf trap or receiving means 30.
- the leaf receiving means is also coupled by a conduit 32 to the inlet side of an auxiliary or booster pump 34 whose discharge operates a local area turbulence system generally designated by the numeral 36.
- an automatic turbulence system 36 is preferred because it operates continuously and contemporaneously with the stationary jets of the present apparatus, as will be seen, and tends to keep the leaves in motion in the localized region in which it is operating.
- the system 36 can be of that type which is movable through successive smaller or localized regions of the pool, employing flexible hoses from which streams or jets of water are discharged. The reaction from the jets moves the hoses in a sinuous fashion, directing the discharged water randomly over the adjacent pool surfaces and physically scrubbing the hoses against the pool surface.
- Rotary jets can also be used, as will be seen.
- the turbulence system 36 is effective to place smaller contaminant particles in suspension for circulation to the filter, and suspend and move leaves a short distance within the localized region in which the system 36 is operating.
- a stationary jet or fixed nozzle means or nozzle 38 is mounted to a side of the pool approximately midway between its opposite ends. It is coupled to the outlet conduit 22 and oriented to direct its steady stream or jet of water downwardly and along a predominantly unidirectional fixed direction pathway 40 extending down the side and across the bottom of the pool, as indicated by the arrows seen in FIG. 2.
- a second stationary nozzle 42 is mounted to the bottom of the pool in the pathway 40 and oriented to direct its steady stream or jet of water across the bottom of the pool in a path coincident with the pathway 40 to augment and accelerate the flow of water in the pathway.
- the nozzle 42 is coupled to the pump outlet conduit 22, but by a branch conduit 44.
- a pool drain or leaf collection inlet means 46 is preferably located in the pool bottom adjacent the side of the pool opposite the stationary jet 38. It is fixed in position in the pathway 40 to intercept and receive leaves carried by the stream of water which defines the pathway.
- the system of FIG. 2 is intended for use with a comparatively small pool, such as a 15 foot by 30 foot pool for example.
- the system of FIG. 7 is also designed for a smaller pool but it employs a particular local area turbulence system operative over larger local areas, as compared to a sweep hose system which must operate on successive smaller local areas.
- the system illustrated in FIG. 7 employs a pair of rotary nozzles 48 of any suitable type, such as the type disclosed in U.S. Pat. No. 3,506,489 (Baker) issued Apr. 14, 1970.
- the angular direction of the jet from each nozzle 48 is changed from one angular sector to another by a valve means which is associated with the nozzle and which is effective intermittently to shut off and turn on the flow of water to the nozzle and cause it to shift the jet stream position.
- the Baker rotary nozzle is representative of rotary nozzles for radially directing a stream of water successively to successive sectors of the pool for relatively prolonged periods of time to extend the path of the discharged water, and thereby induce eddies or turbulence over a relatively widespread local region of the pool. Any of these nozzles can be used in the present apparatus.
- the pair of rotary nozzles 48 provides sufficient turbulence in the opposite halves of the pool to move leaves about in random fashion along the water flow paths indicated by the arrows.
- the leaves drifting into or encountering the more swiftly flowing unidirectional steady streams or pathways 40 provided by the stationary jets 38 and 42 will be carried along those pathways.
- the operation of the system of FIG. 7 is like that of FIG. 2.
- FIG. 8 illustrates a local area turbulence system better suited for relatively large pools in the order of 40 feet by 80 feet.
- a plurality of rotary nozzles 48 are employed at regular spaced intervals throughout the pool.
- the nozzles 48 are arranged in parallel longitudinal and transverse rows as illustrated.
- the local regions in which turbulence is induced by each of the nozzles 48 is schematically indicated by the partial or full circles adjacent to the nozzles.
- the system of FIG. 8 also includes a plurality of stationary nozzles 42 arranged in parallel longitudinal and transverse rows.
- the longitudinal rows establish longitudinally directed primary leaf gathering streams or pathways 40, as indicated by the longitudinally directed arrows, while the nozzles 42 located between the longitudinal rows direct streams of water in opposite, lateral directions to establish secondary streams or pathways, as indicated by the arrows 49.
- the mixture of leaves and water passing into the leaf receiving means is carried by a connecting conduit 50 to the base of a cylindrical collector tank 52 which forms part of the externally located leaf collecting means of the receiving means 30.
- the tank is mounted within a suitable opening in the pool deck 54 and its open upper end is closed by a removable cover 56.
- a mount 58 disposed within the tank 52 includes a downwardly oriented cylindrical flange 60 which slidably fits over the upper extremity of the cylindrical connecting conduit 50.
- the mount 58 further includes an arcuate seat or recess which receives a pivotable valve means or closure 62.
- the closure 62 can be pivoted from the open position illustrated in FIG. 4 to the closed position illustrated in FIG. 5.
- water and leaves are free to flow through the mount 58 into the interior of a foraminous leaf collector or bag 64.
- the lower end of the bag fits over a groove in the periphery of the mount 58 and is removably held in place by an elastic cord or ring 66.
- the leaf bag 64 can be made of any suitable material, such as rigid screening or other apertured material, but the foraminous flexible bag 64 is preferred. It is illustrated in FIG. 3 in the shape it would assume with water passing into it from the conduit 50. This water passes through the bag and into the tank 52, and the remaining leaves collected in the bag 64 are easily removed by taking off the cover 56 and slidably separating the mount 58 from the conduit 50. This is done by pulling upwardly on an elongated, vertically oriented handle 68 which is also used for pivoting the closure 62.
- the base of the tank also includes a flanged opening for coupling the tank 52 to the conduit 16 on the inlet side of the pump 18.
- the outlet side of the pump 18 is coupled to a tank inlet conduit 70 which discharges into the base of the tank 52.
- the upper extremity of the conduit 70 includes one or more small apertures which serve as venturi nozzles to discharge water at increased velocity through the water in the base of the tank 52 and into a tank discharge conduit 72 which empties into the pool 10.
- the venturi effect enhances rapid flow of water from the tank 52 back into the pool.
- booster pump 34 which is coupled to the tank 52 is helpful to further increase the rate of flow of leaves and water to the leaf bag 64 from the enlarged or oversize connecting conduit 50.
- the height of the tank 52 is made such that the normal draw down or lowering of the operating level 74 of water in the tank places the level lower than the pool waterline 76, as seen in FIG. 3.
- This differential in water level improves discharge flow from the tank 52 through the tank discharge conduit 72. It also allows a back flow of water from the pool to the tank 52 to maintain pump suction should the connecting conduit 50 become blocked and fail to allow water to come into the tank from the collection inlet means 46.
- the rotary nozzles 48 will develop eddies or turbulence in a pair of relatively widespread local regions at opposite ends of the pool. Leaves and other foreign debris will be moved randomly toward the fixed direction, relatively swiftly flowing stream or pathway 40 developed by the stationary nozzles 38 and 42 which crosses the local turbulent regions. The leaves will be captured by the pathway 40 and discharged into the inlet means 46 of the leaf receiving means 30. From there they are carried by the connecting conduit 50 into the interior of the leaf collector bag 64.
- the leaves are retained in the bag, and separated water passes into the tank 52 and then back to the pool through the tank discharge conduit 72.
- the venturi nozzles of the conduit 70 enhance the rate of this discharge. As previously indicated, the rate of discharge is further accelerated by connection of the booster pump inlet to the tank 52.
- the pathway 40 is always directionally oriented to terminate at the inlet to the leaf receiving means 30. Its continuous flow develops a momentum extending the pathway 40 the full length of the average size pool, and it is not appreciably diminished or deflected in direction by the local eddies developed by any turbulence system 36. Consequently, any leaves located in or adjacent the pathways are captured and carried to the inlet means 46. Streams of water which are random or which sweep through a pool sector are not relied upon for leaf removal, but serve only to develop local area turbulence to ready the leaves for capture by the steady state flow of the pathway 40 or pathways, as the case may be.
